GetCVarFixed

fixed a_GetCVarFixed(str name)

fixed a_GetUserCVarFixed(int player, str name)

ZDoom doesn't provide a version of GetCVar that returns the value of a float cvar.

ACSUtils implements a_GetCVarFixed and a_GetUserCVarFixed by calling GetCVarString to retrieve its value as a string and parsing that string using ACSUtils number parsing functions.

The functions have an a_ prefix, because GDCC has its own unrelated GetCVarFixed function, which would cause a compiler error in GDCC if the ACSUtils functions were called just GetCVarFixed and GetUserCVarFixed.</note>
